    Ditter V21 (A31s, 1Gb RAM)

    Hello friends!
    I am not professional, please don't beat))) Better help me!
    I have Ditter V21. I added big radiator, because it was overheating.
    Now it works ok. I don't have any poor emotions with it. It works better than my Imito MX2, because WIFI is much better. One problem is what "screen percent" comes to default after each reboot, so picture has black frame over the border. After reboot, the slider of "screen percent" is in choosen by me the rightmost position. But in fact there is a frame around the screen like the default settings. Choosen position that displayed does not correspond real settings. But I fixed this issue in my LCD TV settings. I don't know, is there interpolation. Picture and fonts look clear, not blurr.
    Second problem, what sometimes, if you do many actions, interface can freeze for 2 seconds. If you don't want to wait 2 seconds, you can immediately press HOME button, and it immediately stops freeze. This issue is not so big problem, as I feel. I don't find that problem on clear system after hard reset. Maybe one of post installed apps makes that.
    I tried NFS Most Wanted. It shows x1.5 more FPS than Imito(rk3066). That's cool.
    I don't try to see 3D or Full HD video, because i don't need this. I always use only mkv(h.264) 2-3Gb. Because it downloads fast. And usually I use it for watch TV over internet. HD channels look OK.
    It has two hardware buttons on board. One is firmware update mode. Second - is hard reset.
    I can't find any firmware files in internet.
    I got root with update for Onda tablet(A31).
    I saved firmware's partition's images via terminal emulator. Is it right action?
    It wrote, what it has Android 4.2.2 kernel version 3.3.0. How can I check, is it true?
    I want to add init.d support. How can I make this?
    I want to change kernel to 1080. Is it real?
    Has any idea, how to fix issue with "screen persent"?
    If you have any questions, feel free to ask.
    On other forum, one man wrote, what build.prop is like MK823. Is firmware compatible?

    Hi.. and welcome
    Indeed the unit looks like a mk823 ( like i have)
    Mk823: pcb v1.2 (no buttons )
    V21: pcb v1.3 (buttons)
    The firmware seems identically to the mk823 4.2 posted at download-section freaktab

    It was smart adding a cooler/heatsink the unit does run hot
    -mk823 has a heatsink, but i also replaced it.. with a bigger one

    Possibilitie..
    -there is 'elektric' custom fw for the mk823..that might work on your unit ( android 4.1.1)
    --it has init.d and many other tweaks

    For the 2 sec delay.. use a tool called 'android tuner'
    -governors 'max power' from 0 to 1 (disables cores going to sleep/offline)
    -more cpu throttle from 120 mhz to 720/1ghz ( using multi-core button)
    The screen issue.. try 'lcd density' app or just leave the device On

    Note..
    Overclocking app.. dont work.. it will only change core0
    SPMC 4.1 (xbmc) works really great (but dont use adv.xml cachesize 0, it messup the system)

    Anway.. Cheers and goodluck

        Hi all - I also own a Ditter V21 and I'm quite satisfied with it.

        But... I'd like to make an upgrade, if it was possible.

        Denn1 - have you tried the Mk823 firmware, by chance?

          I have installed PhoenixSuite but I haven't managed yet how to make it recognize the device to enter flash mode. Have you any clue / suggestion to provide?
          Thanks! Fabio
